This paper aims to demonstrate how the huge amount of Social Big Data available from tourists can nurture the value creation process for a Smart Tourism Destination. Applying a multiple-case study analysis, the paper explores a set of regional tourist experiences related to a Southern European region and destination, to derive patterns and opportunities of value creation generated by Big Data in tourism. Findings present and discuss evidence in terms of improving decision-making, creating marketing strategies with more personalized offerings, transparency and trust in dialogue with customers and stakeholders, and emergence of new business models. Finally, implications are presented for researchers and practitioners interested in the managerial exploitation of Big Data in the context of information-intensive industries and mainly in Tourism. 相似文献

Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow 总被引：1，自引：0，他引：1

Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample evaporation in polymeric and hybrid devices, realized by glass microchannels for avoiding water diffusion toward the elastomer used for chip fabrication. The method dramatically reduces water evaporation in PCR devices that are found to exhibit optimal stability and effective operation under oscillating-flow. This approach maintains the flexibility, ease of fabrication, and low cost of disposable chips, and can be extended to other high-temperature microfluidic biochemical reactors. 相似文献

Purpose: To describe the results of showing farmer learning videos through different types of volunteers.
Design/Methodology/Approach: Semi-structured interviews with volunteers from different occupational groups in Bangladesh, and a phone survey with 227 respondents.
Findings: Each occupational group acted differently. Shop keepers, tillage service providers, agricultural input and machine dealers reached fairly small audiences. Tea stall owners had large, male audiences. Non-governmental organisations and community-based organisations, reached more women. The cable TV (dish-line) operators showed the videos on local TV, but some were reluctant to do so again. The Union Information Service Centres showed the videos and reached women viewers. Half of the official government extension agents surveyed also showed the videos publically.
Practical Implication: This video featured maize, wheat and rice seeding machinery. Because the machinery is complex and requires hands-on training, this first video aimed to expose tillage and sowing service providers and farmers to the machinery, without trying to teach them how to use it. But some farmers were so interested that they watched the video many times to learn more about the equipment. Before farmers and service providers decide to buy machinery for direct seeding, they still want to see and learn from demonstration plantings, to examine first-hand how the crop behaves when planted with the new equipment.
Originality/Value: Video can be an effective way of sharing high-quality information with a large audience, if properly distributed. 相似文献

Modelling and analysis of a basilica under earthquake loading 总被引：1，自引：0，他引：1
In this paper a basilica-type church is analysed in order to assess its structural behaviour and seismic vulnerability. For this purpose, an effective two-step procedure has been used, consisting of: (a) 3D static and dynamic linear analyses of the structural complex, and (b) 2D nonlinear push-over analysis of the single macro-elements. The results obtained through push-over analyses have been compared to the collapse loads derived from limit analysis, proving the ability of finite element (F.E.) nonlinear model to provide reliable simulation of the actual response of masonry elements. Then, the strength demand on each single structural macro-elements, resulting from the 3D linear analyses, has been compared to the macro-element ultimate strength capacity. The comparison demand vs. capacity has been carried out for all transversal and longitudinal macro-elements of the church, allowing a direct, though approximate, assessment of the seismic safety level of the church. The comparison demand vs. capacity confirms the susceptibility of this type of buildings to extensive damage and possibly to collapse, as frequently observed. The insertion of rigid diaphragms, which represents a widely used retrofit technique, has also been investigated; such intervention triggers concentration of strength demand in the stiffest macro-elements, so that the seismic capacity of the building is not necessarily increased. 相似文献

Peggy McCardle Joan Mele‐McCarthy Kathleen Leos 《Learning disabilities research & practice》2005,20(1):68-78
Although little is known about learning disabilities (LDs) in English language learners (ELLs), there is a substantial knowledge base about the identification, assessment, and intervention of and for LDs in monolingual native English‐speaking students. Building on this knowledge, participants at an October 2003 National Symposium on Learning Disabilities in English Language Learners were asked to suggest research questions, priorities, and suggestions on how to build the necessary infrastructure to address critical research needs. In the discussions that took place, important themes emerged: (1) identification and assessment of LD and/or reading disabilities (RD) in ELLs (ELL/Ds), (2) understanding of the language and literacy developmental trajectories of ELLs, (3) understanding of the individual and contextual factors affecting outcomes, (4) the intersection of all of these areas with neurobiology, and (5) developing and testing the effectiveness of interventions for learning disabilities in ELL/Ds. These themes, and the research agenda that was forged around them, are presented. In addition, the practice implications of this agenda are presented, along with some suggestions for current practice while we await future research findings. 相似文献

Toddlers’ Self-Recognition and Progression From Goal- to Emotion-Based Helping: A Longitudinal Study
Research has typically used cross-sectional designs to draw conclusions on the development of helping. This study aimed to examine the development of instrumental and empathic helping behaviors as they emerge, and assess how self-recognition might moderate this progression. Seventy-two children (14- to 25-months at T1) were assessed over four monthly sessions. Participants’ individual response patterns showed instrumental helping to be a necessary precursor to empathic helping for 55.77%–67.92% of children who helped during the study. Self-recognition emerged before empathic but not instrumental helping, yet did not directly influence helping behavior. 相似文献

Stepping stones to others' minds: maternal talk relates to child mental state language and emotion understanding at 15, 24, and 33 months 总被引：4，自引：0，他引：4
This continuation of a previous study (Taumoepeau & Ruffman, 2006) examined the longitudinal relation between maternal mental state talk to 15- and 24-month-olds and their later mental state language and emotion understanding (N= 74). The previous study found that maternal talk about the child's desires to 15-month-old children uniquely predicted children's mental state language and emotion task performance at 24 months. In the present study, at 24 months of age, mothers' reference to others' thoughts and knowledge was the most consistent predictor of children's later mental state language at 33 months. Vygotsky's zone of proximal development provides a framework within which maternal talk, first, about the child's desires and then about others' thoughts and knowledge scaffolds children's social understanding. 相似文献

Reading minds: the relation between children's mental state knowledge and their metaknowledge about reading 总被引：1，自引：0，他引：1
The relation between children's mental state knowledge and metaknowledge about reading was examined in 2 studies. In Study 1, 196 children (mean age = 9 years) were tested for verbal ability (VA), metaknowledge about reading, and mental state words in a story task. In Study 2, the results of Study 1 were extended by using a cross-lagged design and by investigating older children (N = 71, mean ages = 10 years at Time 1 and 11 years at Time 2) for mental state knowledge, metaknowledge about reading, and VA. Results showed a significant relation between early cognitive (but not emotion) mental state knowledge and later metaknowledge about reading, controlling for VA. Results suggest close links between different aspects of children's knowledge about the mind. 相似文献
